ROAD-DRAG.

Specification of Letters Patent.

Patented July 2, ll9l3.

Application filed November 17, 1916. Serial No. 131,904.

T 0 all whom it may concern Be it known that I, ALrHEUs l-l. TANNAR, a citizen of the United States, residing at Mapleton, in the county of Bourbon and State of Kansas, have invented a new and useful Road-Drag, of which the following is a specification.

The device forming the subject matter of this application is a road drag, and one object of the invention is to'provide a drag which will first cut the material loose horizontally, then carry the material laterally, without producing a side draft, and finally smooth down and compact the surface of the roadway.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description procoeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, withoutdeparting from the spirit of the invention.

In the accompanying drawing Figure 1 shows in top plan, a road drag constructed in accordance with the present invention; and

Fig. 2 is a side elevation of the road drag shown in Fig. 1.

In carrying out the present invention there is rovided a frame of substantially rectangul ar outline and comprising side bars 1 and 2 and end bars 3 and 4:. The side bars and the end bars may be connected by angle members 5 or in any other suitable manner. Disposed between the side bars 1 and 2 and located parallel thereto is an intermediate bar 6 connected by angle members 7 or otherwise with the end bars 3 and 4.

Fixed to and depending from the side bar 2 near to the forward end thereof is a yoke 8 held in place by securing elements 9. A similar yoke 10 is held by securing elements 11 on the intermediate bar 6 near to the forward end of the intermediate bar. The yoke 10 is located slightly behind the yoke 8. A knife 12 is attached to the yokes 10 and 8 by securing devices 1 1 of any desired kind. The knife 12 has a sharpened forward edge 15. The numeral 16 denotes a knife like the knife 15 and arranged parallel to the knife 15. By means of yokes such as those shown at 8 and 10, the knife 16 is connected with I(She intermediate bar 6 and with the side Mounted on the bars 1, 6 and 2 are triangular braces 17 carrying a scraper composed of a board 17 and a face plate 20, these elements being held by securing devices 21 to the front portions of the braces 17 which are attached by securing devices 18 to the bars 6, 1 and 2. The scraper above described stands vertically, but it is inclined with respect to the draft line, as clearly indicated in Fig. 1 of the drawings. The knives 16 and 15 are also inclined with respect to the draft line, the knives 15 and 16 on the one hand, and the scraper on the other I hand being disposed at an acute angle to each other.

Mounted on the bars 1, 6 and 2 are triangular braces 22, held in place by securing elements 23. The forward portions of the braces 22 slant upwardly, and thereto is at tached by securing elements 25, a board 24, including a face plate 26 having a lip 27 which extends along the forward edge of the board. The parts 26 and 24: constitute a smoother. It will be understood that the smoother above described may be disposed at any desired angle with respect to the hori zontal, this angle being either greater or less than the angle shown in Fig. 2.

In the side bars 1 bear to the forward ends thereof, holes 29 are formed, and in any of these holes may be mounted clevises 30 connected with converging draft rods 31. By mounting the clevises 30 successively in the holes 29, the cutting efl'ect of the knives 12 and 16 on the ground may be regulated.

Mounted to rock in the intermediate bar 6 near to the forward end thereof is a shaft 32 having a crank 33 to which is attached a wheel 34. A lever 35 is assembled with the crank 32 and carries a latch mechanism 36 adapted to coact with a segment 37 secured to the intermediate bar 6.

Boards 40 may be mounted on the frame above described, to constitute a platform on which the operator may stand.

In practical operation, the knives 12 and 16 cut down the surface of the roadway, and the loosened material is received by the inclined scraper 20-19, and is carried laterally, to one side. Owing to the relative angles existing between the scraper 1920,

upon the one hand, and the knives 16 and 12 upon the other hand, with respect to the draft line, the parts above mentioned eooperate to prevent a side draft. The smoother 2l26 finally passes over'the surface of the roadway and imparts a finish thereto, and serves-to pack down the surface of the roadway. The platform 40, ordinarily, is of sufficient length so that the operator standing thereon can shift his weight to any desired point, tofacilitate the operation of the structure.

At times it is desirable to lift the forward end of the frame, and for this purpose the wheel 34: andattendantparts are, provided. Obviously, by manipulating the lever 35,;the shaft 32 will be rocked, bringingthe wheel 3f into contactwith the ground. The. crank 33 is forwardly presented, and the forward end of the frame will ride up onto the wheel, thus swinging the knives 12 and 16 cleanof the ground, and permitting the knives to clear bridges and other obstructions located along the roadway.

The device forming the subject matter of this application is adapted peculiarly to smooth the surface ofa turnpike as soon as it dries, after a rain storm. A quantity of earth can be kept in front of the,.-scraper 2019, at all times, if the operatorwill merely step forward on the platform 20, and put more weight on the knives 12 and 16. The loosened dirt will fill in depressions or ruts left in the-roadby travel when the ground is wet. The scraper 1920 is set at an acute angle to the draft line, in order to deposit any surplus dirtinthe middle of the roadway, the structure herein disclosed, ordinarily, being drawn alongone side of the roadway, and then back. along the other side of the roadway. In this manner, the lateral grade of the roadway will be preserved, andsurface :water will be permitted to drain olf readily into the side ditches. The machine herein disclosed is of light construction, so that it can be drawn readily by twodraft animals and handled by one man.

Having thus described the invention, what is claimed is A road drag comprising a frame made up of ends, side bars connecting the ends, and an intermediate bar connecting the ends; a pair of horizontal knives disposed in a pproximate parallelism and placed at an acute angle to the draft line, the outer ends of the knives being secured to the side bars, and the inner ends of the knives being spaced apart longitudinally of thedraft lineand being secured to the intermediate bar; a lifting device carried by the intermediate bar and located between the inner ends of the knives; a scraper extended from one side bar to the other andlocated to the rear of the knives, the scraper being disposed at an acute angle to the draft line and at an acute angle to both knives; anda fixed smoother disposed to the rear of the scraper, the smoother extending from one side bar to the other and beingdisposed at right angles to the draft line, the lower surface of the smoother being upwardly and forwardly inclined at an angle to the horizontal.

In testimonythat I claim the foregoing as my own, I havehereto affixed my signature in the presence of two witnesses.
